Sphingomyelin content of AL-enriched IF … A saponifiable lipid is part of the ester functional group. They are made up of long chain carboxylic (of fatty) acids connected to an alcoholic functional group through the ester linkage which can undergo saponification, hence the name. The fatty acids are released upon basic catalyzed ester hydrolysis. The primary saponifiable lipids are triacylglycerides, glycerophospholipids, and the sphingolipids.
